Strengths and weaknesses
- +Waterfall enrichment chains 150+ data providers under one subscription, materially raising email/firmographic match rates versus any single source
- +Combines enrichment, AI web research (Claygent), and signal monitoring (funding, hiring, job changes, tech installs) in one platform
- +Spreadsheet-style table UI plus Clay University make complex multi-step enrichment accessible without code
- –Dual credit/action model causes fast, hard-to-predict credit burn; auto-recharge billing reportedly fires without advance warning
- –Steep learning curve, reviewers cite hours in week one and 2–3 weeks before workflows are reliable
- –Phone/mobile number coverage is weak (~30–35% match rate)
- +Free API access stated in the docs
- +Plan-tiered published rate limits and per-endpoint credit costs
- +Search over 200M+ contacts and 30M+ companies with 30+ filters
- –Unused credits expire every billing cycle
- –Per-user pricing multiplies for teams
- –Mobile reveals cost 10 credits
